How do we use the "Equivalent fractions"to convert a fraction to a percentage?

Question

Help please, been struggling with this question for a long time.

Answer 1

You can set up a proportion.  

 

For example, to convert a fraction such as 11/17 to a percent, use the 

 

proportion 11/17 = x/100

 

                 17x = 1100

 

                    x = 1100/17 ≈ 64.7% 

Answer 2

You want the equivalent fraction to have a denominator of 100, since percentages are numbers out of 100.

 

1 / 2 = 50 / 100 = 50%

 

4 / 5 = 80 / 100 = 80%

 

1 / 5 = 20 / 100 = 20%

 

3 / 4 = 75 / 100 = 75%

 

 

And so on.
